Formaldehyde releasing agents

Various formaldehyde condensates have been developed to reduce the irritancy associated with formaldehyde while maintaining activity and these are described as formaldehyde-releasing agents or masked-formaldehyde compounds.

Cosmetic preparations that contain formaldehyde donor compounds release formaldehyde in the presence of water. Very often, these are water-based preparations, such as shampoos. The presence of released formaldehyde is not required for the antimicrobial action of the compound and is therefore regarded as an nuisance however, this depends on the chemical formula as a whole. In the end, increasing use of formaldehyde-releasing compounds may lead to an increase in the incidence of contact allergy (Kranke et al. 1996). Formaldehyde-releasing agents include ... 

Some biocides are formaldehyde-releasing agents, and this may sometimes be the basis of their biocidal properties. Those described as sensitisers include ... 

The antimicrobial effect of formaldehyde and formaldehyde releasing agents (III.3) may be reduced by ammonium ions (formation of hexamethylene tetramine (III.3.3.1)).

Another formaldehyde-releasing agent is hexamine (hexamethylenetetramine, methenamine). Hexamine is microbiologically inactive but breaks down by acid hydrolysis to release formaldehyde [34]. 

Still in the medical field, gaseous formaldehyde, usually in the form of a formaldehyde-releasing agent such as paraformaldehyde, was used for fumigation of large areas although this practice has been discontinued because it was found to be of little value [325]. Nevertheless, its use is still recom-... 

Shelf life of an additive Preservation of carbonate dispersions [I, 5.9.] for transportation from the manufacturing site to the paper machine by road or train can take several weeks. Filler preservation with OPP (orthophenylphenolate) [II, 7.4.1a] or formaldehyde release agent (i.e. dihydroxy-dioxahexane [II, 3.1.4b.], hexahydro-triethyl triazine [II, 3.3.19.]) can be very effective and not affected by ORP reduction in a totally closed tank. But the same filler, when stored in the mill in a container with very fast circulation (and with a storage time from a few hours to a few days) can be treated with Isothiazolinones and bromonitropropanediol PI, 17.14.] through one or a few injections per day.
